| 7889 | Our concept of consciousness is crude, and lacks theoretical articulation [Papineau] |

| 7890 | Maybe a creature is conscious if its mental states represent things in a distinct way [Papineau] |
| 7885 | The 'actualist' HOT theory says consciousness comes from actual higher judgements of mental states [Papineau] |

| 7860 | The epiphenomenal relation of mind and brain is a 'causal dangler', unlike anything else [Papineau] |
| 7862 | Maybe minds do not cause actions, but do cause us to report our decisions [Papineau] |
| 3513 | How does a dualist mind represent, exist outside space, and be transparent to itself? [Papineau] |
| 3514 | Functionalism needs causation and intentionality to explain actions [Papineau] |

| 7865 | Supervenience can be replaced by identifying mind with higher-order or disjunctional properties [Papineau] |

| 7872 | Teleosemantics equates meaning with the item the concept is intended to track [Papineau] |
| 22283 | Compositionality should rely on the parsing tree, which may contain more than sentence components [Potter] |
